Arschfick-umkehr

I've been dating this curly blonde for 5 months, but all we did was oral sex and vaginal fucking, no anal at all. I got some advice from an Internet buddy of mine and did exactly what he told me. I started with sliding a finger in my girlfriend's ass, then made it two and finally replaced them with my hard cock when I felt she was ready for it. Her reaction exceeded my expectations - she was screaming of pleasure and demanding I fucked her in the ass like a dirty slut. What a turnaround!
